Hi N.,
People say age 2 is when you should get rid of the pass, BUT, personally, I think 2 1/2 to 3 is a better age. My 4 year old had a brand new baby sister when she was 2, and then was potty training, so, between 2 and 2 1/2 didn't seem reasonable for us to ask her to give up her "pass". She was almost 3, we explained to her that she was 3, a big girl and it was time to give her "pass" to the pass fairy. The first night she wanted a pass, but, was old enough to remember that she was giving up the pass, and the pass fairy was coming. What is funny, is that after the first night, she was so excited to give another pass to the pass fairy, so, we did actualy have the pass fairy come a few nights! BUT, that was that. (We told her that the pass fairy brings her passes to new babies who need a pass..........since she doesn't anymore, because she is a big girl).
My 2 1/2 year old is aware that soon she'll be giving her pass to the pass fairy. I'm sure some people would disagree, but, I don't do too many things at the same time to not stress them out. I'm not going to do anything about her pass until after summer vacation since we are out and about and away so much. I find that if you pick one thing, potty training, losing the pass.....do it when there is no other stress and when that can be the focus, otherwise, you're setting yourself up for disaster.
I guess I didn't feel the pressure to get rid of the pass too early. I kind of felt like it would have been traumatic for her at age 2, but, by age 3, she was old enough to unserstand and realize that she'd get a little gift and that she didn't need it anymore because she was a big girl. I say, don't rush, wait til you think your child is old enough to understand, (within reason of coarse!). There is such a big difference in understanding between ages 2 and 3.
I had to hear from people that she was too old for a pass, but, personally, I have decided that those people who give you "ADVISE", which is more of an insult....they are really not trying to help, they're just talking and not realizing that #1, they are being insulting, #2, none of their beeswax!!!!
Hope my experince is of some help.
Good luck!!!
